This study investigates the impact of consumer buying behavior on the patronage of Small and Medium Enterprises (SMEs) in Bauchi Metropolis, focusing on four key behavioral factors: purchase intention, purchase frequency, brand loyalty, and product preference. Despite extensive literature on consumer behavior, many SMEs continue to struggle with low customer retention and inadequate patronage, often due to a fragmented understanding of these interrelated factors. The study adopts a survey research design and uses structured questionnaires to gather data from 300 randomly selected SMEs out of a population of 1,015, as listed by the Bauchi State Ministry of Commerce and Industry. Data were analyzed using SPSS version 20.0, employing both descriptive and inferential statistical techniques, including correlation and multiple regression analysis. Findings revealed that all four behavioral factors showed strong positive correlations with consumer patronage. However, regression results indicated that none of the variables had a statistically significant predictive effect when tested individually, suggesting that while consumers express favorable attitudes, these alone may not translate into consistent purchasing behavior. The study concludes that SMEs should not rely solely on isolated behavioral cues but should adopt holistic strategies involving service quality, digital engagement, emotional branding, and cultural alignment to sustain customer patronage. The study recommends the integration of multi-dimensional marketing strategies and customer analytics to better understand and respond to evolving consumer behavior.
